SOURCES: Social Security Administration. For years before 2000, Annual Statistical Supplement to the Social Security Bulletin, based on the Master Beneficiary Record, various sampling rates; from 2000 through 2001, Annual Award and Termination Transaction file, 1 percent sample; data after 2001 are 100 percent data.

NOTES: Age in year of award from 1960 through 1984; age in month of award after 1984.

Data exclude closed period awards in 2002 and 2003 and expedited reinstatement cases since 2002.

Starting with 2007, age is based on date of entitlement and not date of award. Entitlement can be retroactive and thus precede the date of award.

NOTES: Data exclude closed period awards in 2002 and 2003 and expedited reinstatement cases since 2002.

Data from 1964 through 1966 are not available. Before 1995, diagnostic data for cases awarded at the appeals levels were estimated on the basis of the diagnosis of cases allowed at the initial disability determination level.

Effective 2001, the Social Security Administration initiated a special review of 130,000 Supplemental Security Income (SSI) recipients who are potentially eligible for Social Security disability benefits because of earnings while receiving SSI. Many of these claims awarded since 2001 were for individuals under the age of 35 who were diagnosed with a mental disorder.

-- = not available.

a. AIDS and HIV records are counted in "Infectious and parasitic diseases." Before 1990, they were included in "Other."

b. Mental retardation (now referred to as intellectual disability) was not identified separately before 1995.

c. Beginning with 2002, several ill-defined impairment codes were reclassified and added to "Unknown."

SOURCES: Social Security Administration. For years before 2000, Annual Statistical Supplement to the Social Security Bulletin, based on the Master Beneficiary Record, various sampling rates; from 2000 through 2001, Annual Award and Termination Transaction file, 1 percent sample; data after 2001 are 100 percent data.

NOTES: Data exclude closed period awards in 2002 and 2003 and expedited reinstatement cases since 2002.

Before 1995, diagnostic data for cases awarded at the appeals levels were estimated on the basis of the diagnosis of cases allowed at the initial disability determination level.

Effective 2001, the Social Security Administration initiated a special review of 130,000 Supplemental Security Income (SSI) recipients who are potentially eligible for Social Security disability benefits because of earnings while receiving SSI. Many of these claims awarded since 2001 were for individuals under the age of 35 who were diagnosed with a mental disorder.

Starting with 2007, age is based on date of entitlement and not date of award. Entitlement can be retroactive and thus precede the date of award.

-- = not available.

a. AIDS and HIV records are counted in "Infectious and parasitic diseases." Before 1990, they were included in "Other."

b. Mental retardation (now referred to as intellectual disability) was not identified separately before 1995.

c. Beginning with 2002, several ill-defined impairment codes were reclassified and added to "Unknown."
